Hi everyone, I'm using the lastest ifort 12.1.5 and I'm tesing the pgo (profile-guided optimization) feature, but encoutered problems. Here's my program, a quite simple hello world: [fortran]program main print *, "hello" end program main [/fortran]
then i compile it like this:
[bash]ifort -prof-gen hello.f90
[/bash] then I run the program
[bash]./a.out[/bash]
and then compile it again:
[bash]ifort -prof-use hello.f90[/bash] but I got the following error message:
[bash]/tmp/hello.f90(1): warning #11507: Value profiling mismatch for 'MAIN__'.[/bash] Does anyone know why? did I miss something? Thanks.
